Method for protection of contactless signal transmission from a transmitter to a receiver, and a signal transmission device
First Claim
1. A method for protection of contactless signal transmission from a transmitter to a receiver, with the signal being subjected to reshaping before being transmitted, such that at least one of reproducibility and transmissibility are exacerbated, and the reshaping can be detected by a detector in the receiver.

Abstract
For contactless signal transmission, a signal transmitted by a transmitter is subjected to reshaping in such a manner that its reproducibility and/or transmissibility are/is exacerbated, but also in ;uch a manner that the reshaping can be detected in a detector in the receiver. In this way, the signal transmission is protected against the possibility of a deliberately short range between the transmitter and receiver being enlarged by manipulation by an intermediate transmitter/receiver.

3. A signal transmission device, comprising:
-
a transmitter having a reshaping device, which subjects a signal sent from the transmitter for wire-free signal transmission in such a manner that at least one of reproducibility and transmissibility are exacerbated; and
a receiver having a detector which supplies an output signal when reshaping is present. - View Dependent Claims (4, 5, 6, 7, 8)
